  1. 6. Interference and Energy Conservation in Phased Antenna Arrays and Young’s Double Slit  Experiment

    University essay from Institutet för rymdfysik, Uppsalaavdelningen; Institutionen för fysik och astronomi

    Author : Andreas Lundin; [2012]
    Keywords : Interference; energy conservation; double slit; antenna; antennas; array; phased; electromagnetic coupling;

    Abstract : The interest in creating and detecting electromagnetic waves carryingangular momentum in such a way that they form helical wavefronts,so called "twisted light'', has increased in recent decades.One possible way of generating such waves at radio frequenciesis to use a circular phased antenna array, where a larger relativephasing of the antenna elements corresponds to more twist of thewavefront per wavelength.

  4. 8. Quantification of temporal changes in metal loads – Moss data over 20 years

    University essay from KTH/Geodesi och satellitpositionering

    Author : Joseph Addai; [2007]
    Keywords : ;

    Abstract : Environmental monitoring, assessment and conservation programmes worldwide have led to the development of scientific and technological methods to study the changes in our environment.
